Introduction

Learn how to configure your agent in YAML

Overview

Agents are configured using a YAML file. The file should define:

• The infrastructure to use (e.g., an EC2 instance)
• Actions to perform within the infrastructure (e.g., installing custom Linux packages)
• Your project’s dependencies (i.e., Python packages)
• Your project’s entrypoint (i.e., what command to use to actually execute your project)
• Environment variables
• Files to download upon the project’s completion

Example

Here’s an example configuration file:

alto.yml

my_cloud_agent:
  infra:
    type: ec2  
    instance_type: t2.micro
    ami_image: ami-0889a44b331db0194
  requirements: requirements.txt
  entrypoint:
    type: script
    cmd: python <script name>.py --arg1 VALUE1
  env:
    ENV_VAR1: "{{ env('ENV_VAR1') }}"

Let’s break this down next.
